The Polbeng II ship has the following main dimensions: Lpp = 9.8 m, B = 1.8 m, H = 1 m, T = 0.6 m, and Vs = 21 knots. Based on the calculation, the ship’s resistance is 5.7 kN, and the engine power is 98 HP. In the ship’s transmission system, the gearbox ratio is 1:3, the shaft has a diameter of 13/4″, and the propeller size is 19 cm x 17 cm. The bearing size is also 13/4″ for greater efficiency in preventing shaft wear during rotation and reducing the level of ship vibrations.
The passenger space in fast ships has seen significant development to accommodate various passenger needs, including densely packed economy class to comfortable business class. The passenger space on the Polbeng II ship has a length of 3 m and a width of 1.6 m.
According to ISO 6954–2000 standards, allowable vibrations in the fast ship’s passenger space should fall within the frequency range of 1–80 Hz to ensure the safety and comfort of passengers during travel. Testing and assessment of vibrations inside the passenger space are conducted by measuring and evaluating the level of vibration speed that occurs. The average vibration speed in the Polbeng II ship’s passenger space, measured from frames 5 to 9, is 1.2 mm/s.
